is one of the most primary concerns of our company, especially with regard to eco-materials. Since the 1960s, all products have been ecologically "conceived" from scratch and have been manufactured using as few chemical components as possible. We make a further contribution to tackling the greenhouse effect by keeping our energy consumption as low as possible during the manufacturing process.
Here are two concrete examples of the mentioned ecologically-sound products:
Oyster shells for paints, bioplastics, glassware, ...
Ostrécal ®, a natural product
is an oyster shell-based concentrate developed by Usine de Kervellerin. This product reduces the use of crude oil and components extracted from quarries (limited resources) whilst also creating a market for oyster farming waste.
From sea to solid land as well as representing a contribution towards social economy: This is the eco-efficient formula developed by Usine de Kervellerin, the family business based in Brittany. As early as 1997, Ms Le Lu, Doctor of Pharmacy and Company Manager, realised that a local and renewable resource remained unused: Leftovers from oyster farming, particularly shells, were seen as unmarketable waste and were treated as such.
Martine Le Lu explored ways to enable this waste product to be processed
After three years of research and development, she presented an industrial procedure that led to the manufacture of Ostrécal®, a natural product, which quickly sold well in various markets.
For instance, paint manufacturers use this product to reduce the use of materials derived from crude oil whilst, at the same time, maintaining quality.
Ostrécal is also popular in the plastics market and, notably, is now an integral part of a biodegradable fibre which is used in the field of 3D printing. This fibre is marketed by Novania under the name Istroflex® and is the result of a collaboration with the ComposiTIC research centre from the University of South Brittany in Lorient. The declared objective is for this product to find its place in a market that is dominated by "Made in China" products.
The local resource was recently further enhanced as, firstly, Usine de Kervellerin awarded the Perlucine Association part of the rights to collect the shell waste and, secondly, also awarded the association with distribution rights for Ostrécal® on its premises. The objective of the Perlucine Association is to reintegrate people that are difficult to employ.
This represents a further contribution towards the easier inclusion of all local participants.
